Description Lars Vogel CLA 2013-02-18 05:40:20 EST 
Looks like we have a small regression in Eclipse 4.2 M5a. Not sure how critical it is but @Focus is called twice.

Please see attached example. The com.example.e4.rcp.todo.product contains the product configuration file. If you start it and select the second parts @Focus is called twice.

The example has been created with N20130214-2000 but we verified that this also happens with Eclipse 4.2 M5a.

Maybe related to Bug 379024?

Still happens in 4.4M2

@Markus, this actually works as intended. If the @Focus method is not putting focus on an SWT control, the framework places focus on the Composite. Once you have an SWT control in your part and can focus() on it, the @Focus method is only called once.
